CHARLES LAURENCE B'URDICK, OF LONDON, ENGLAND.

COIN-WRAPPING MACHINE.

Application led March 5, 1926, Serial No. 92,625, and in Great Britain March 10, 1925.

My invention relates to the class of machines by means of which coins or other articles are put up in roll packets in detinite quantities as or 100 coins and more particularly applies to the class of machines whereby the ends of the packets are spun or crimped by the well known device of a cup shaped spinning head rotated at a considerable speed. My invention consists of a simple form of holder which may be utilized for making up or closing one end of the coin receptacle and also for holdingr the packets when filled with coins and closing the remaining open end. I provide means for quickly adjusting the machine or holder for different lengths of packets and for coins of different diameters and means for advancing the holder to meet the spinning head for closing the ends of the packets. In a suitable casing provided with. guides I mount an adjustable holder which may be V shaped on its upper surface and arranged for verticle adjustment by having geared racks which engage with toothed wheels one set of which is mounted on a spindle which runs longitudinally within the easing the other set interlocking with these.

The shaft is provided with a handle and spring bolt so that it can be secured in various positions in order io bring the centres of the various coin packets in alignment with. the centre of the spinning head.

It is desirable when spinning coin. packets to have a rigid stop or support for the ends of the packets to resist the pressure from the spinning head; to obtain this I provide a rod which will move longitudinally within a cylindrical housing. The rod is provided with a handle extended through the housing and arranged to fall in slots cut in the housing in order to fix it for varying lengths of coin packets as required. This rod can either be made a fixture in the casing and in alignment with the centre of the spinning head or can be raised-and lowered with the coin holder in which case I provide a projection from the end of the rod positioned eccentrically so that as the rod is turned or rotated 180 degrees it will bring the projection higher or lower to accommodate coin packets of larger or smaller diameter. If the invention is used in connection with a rigid spinning head, that is one that cannot be advanced longitudinally I provide rollers for the casing which will permit the whole machine to be advanced along suitable guides to bring the coin packets up to the spinning head.

My invention will be understood by the followingr description with reference to the accompanying diagrammatic drawings oi" which `Figure 1 is a side elevation view,

Figure 1a is a modified form of the lefthand portion of Figure 1,

Figure 2 a plan view,

Figure 3 is the right hand end elevation view, and

Figure li is the left hand end elevation view,

Figures 2. 3 and 4i are drawn to a larger scale than Figures 1 and 1a.

I provide a platform or base 1 on which the machine is mounted and which may serve also as a. support tor a motor 2 carrying a spinning head 3. The spinning head may be secured directly to the shaft of the motor as indicated in Figure l or it may be secured to a jolju'nalled shaft driven from any source oi power as indicated by the belt-pulley 5 indicated in Figure 1'. Then the spinner secured to the motor it is desirable that a brani-:ct 4l; with an adjusahlo centre point (as shown in the drawing) or a ball race be provided to receive the thrust when the spinningoperation takes place. A ball-bearing 6 is indicated to take the thrust in the form shown at Figure 1. A framework or casing 7 provided with slots 8-8 in the base which fit over the pins 9-9 secured to the base 1 and which keep the framework in position as it is advanced or withdrawn on its rollers 10-10.

At one end of the casing 7 is a trough shaped member 11 designed to hold the coin packet and which is raised or lowered as required by means of racks 12-12 secured to the inner part of the trouah and made to engage with toothed wheels 13-13 and 13-13. The set of these wheels 13-13 is secured to a rod or shaft 14 journalled in the casing; this shaft is provided with a handle 15 having a spring bolt 16 which engages with holes 17--17 in the easing te secure the. handle in any desired position. The gear wheels 13 13 enmesh with similar gear wheels 13248.

At the other end ot' the casing T is al rod 18 arranged to slide longitudinally in a tubular casing 19. The rod has a handle 2() which falling in slots 21-21 is so arranged as to provide a rigid end abutment for the coin packets, adjustable for varying lengths of packets.

As slots may be cut on both sides of the tubular easing a great variety o'tf lengths may be accommodated.

The action of the machine is as follows.

A sheet of paper having been Wrapped around a suitable mandrel with a certain part of paper extending beyond the end of the mandrel it is laid in the trough shaped receptacle and the Whole of the machine ineluded in the frame-Work 7 is advanced on its rollers so that the extending paper enters the rotating spring cup 3 and is crimped or turned `dovvn to the end of the mandrel; when the carton so made is lilled with coins or other articles it is again laid in the trough shaped receptacle and the other end spun doWn to the face ofthe outermost coin.

IVhen cartons of varying diameter are to be made the height of the trough is regulated by the handle 15 so as to bring the axis .of the coin packet in alignment with the axis of the spinning head.

As the lengths of the packets Will vary the rod 18 is moved longitudinally in its easing 19 and secured by entering the handie 20 in the appropriate slot to suit the length of the carton or packet.
